Original No. 1,341,583, dated May 25, 19207 Serial No. 348,357, le'dDecember 30, 1919. Application for reissue led July 10, 1920.

To all whom t may concern Be it known that I, THOMAS V. Pinon, a citizenof the United States of America, re`1 siding at Ashland, in the countyof Ash= land, State of Ohio, have invented a new and useful Door-Latch`and Controlling Devices for Combined Hinge and Slide Doors, of which thefollowing is a specification.

My invention relates to locking and controlling mechanism for doors, andis particularly applicable to doors of the combined sliding-and swingingtype, such as used on garages and stables.

The chief object of my invention is to provide simple means whereby thedoors may be effectively locked or latched` in the closed position, saidmeans being easily reversible, and said means being so construct-` edthat it may be used to facilitate the opening of the doors. Otheradvantages not specifically mentioned will be apparent to a mechanicfamiliar with this art from a reading of the following description andan eX- amination of the accompanying drawings inx which Figure l is afront view of a pair of hinged doors arranged to both swing and slidefrom the closed position shown, to the open position illustrated indotted linesv in Fig. 2.

Fig. 2 is a sectional view of the parts shown in Fig. 1 looking down.

Fig. 3 vis a view similar to Fig. 2, but showing the doors arranged'toswing inwardly instead of outwardly, asV shown in Figs. 1 and 2.

Fig. el is a relatively enlarged plan view of my invention with portionof the doors shown in section.

Fig. 5 is a front elevation of the parts shown in Fig. 4.

Fig. 6 is an edge view of a door equipped with my invention.

Fig. 7 is a front elevation of certain cle tails.

Figs. S, 9 and 10 are views of detached details.

I will first describe that type of a door to which my improved lockingmeans is particularly adaptable. In Figs. 1 and 2, I have shown a twosection door the two sections being indicated at 1-2 These sections arehinged together at 3, while the section is hinged to the door casing at4. 5 is a swivel Serial No. 395,386.

, hanger ofany suitable constructionsecured to the upper edge of thedoor to `run along a track 6. The hanger 5 serves to, support the freeedge of the two doorsections 1 2. The hinges B-tare arranged on oppositesides of the door. In the form shown in Figs. 1 and 2, ,the doorsections are intended to buckle outwardly so that they willfold backinto the position yindicated in dotted lines. In Fig. 3 the aforesaidhinges are reversely arranged so that the door will buckle inwardly andfold back into the position shown in dotted lines in said gure. When thedoors buckle outwardly, the latch portion of my invention will belocated on the outside of the door, and when the doors are arranged tobuckle inwardly, the latch is arranged on the inside of the doorsections. The latch is constructedA to automatically operate when thedoors lare closed so as to hold the two sections inline. Frequently suchdoors are equipped with an overhead spring latch bolt which snaps into akeeper glatte in the upper part ofthe door casing.

uch a bolt is indicated at 7 in Fig. 6. M locking mechanism is soarranged that the act of unlatching the door will automatically operateto retract the aforesaid overhead latch bolt.

My automatic latch mechanism comprises the following parts 8 is the baseof a latch carrying frame designed to be screwed or bolted to either oneof the door sections 'adjacentto the break between said sections, and onthe opposite' side from the hinge thereat. In Fig. 4 I have shown saidbase as secured to the section 1. Projecting4 outwardly from the base isa center bearing Q 10-10 are horizontally located spaced jawsfat oneside of said center bearing forming a socket for the tongue 21 laterdescribed; The center bearing is cut away directly behind the jaws 10-10to provideroom for the hub 11 of a swinging latch. 12 is a shaft ,orspindle which passes through the door section 1, and through the centerbearing 9, and through the hub 11 of the latch. 14 is a set screw bywhich the hub may be'locked on the shaft or spindle 12. 15 is a handleat the outer end of the latch by which said latch may be lifted. 16 isthe nose of the latch, the side of said nose nearest the hub 11furnishes an abrupt wall for performing the latch function, while theopposite side of said nose is beveled as indicated at 16a. 17 is a stopon the hub 11 of the latch. 18 is an arm projecting upwardly andrearwardly from the body of the latch near the hub, the function ofwhich arm will be later explained. The nose of the latch is arranged todrop down by gravity in front of the aws 10-10 as b est seen in Fig. 5.That part of the latch between the handle 15 and the hub 11 may beextended laterally to provide in effect wings, each of which ispreferably provided with two passages or holes 192l at its opposite sideedges. The upper and lower sides of the frame upon which the latch ismounted both correspond, so that the latch may be associated with theframe on either side, said latch being detached therefrom, simply byloosening up on the set screw 14 and pulling out the spindle 12. Toattach the latch, the hub of the same is put into place as shown in Fig.4 on the desired side of the frame. The spindle is then re-insertedthrough the center bearing 9 and the hub 11, and the set screw again setup. The other section of the latch mechanism which is attached to theother section 2 of the door comprises a suitable base 20, (see Fig. 9)which is adapted to be screwed or bolted to the door section 2 in frontof the latch proper. Projecting outwardly from the base 20 is a framewhich includes a forwardly projecting horizontally positioned malemember or tongue 21, arranged to project into the space betweenV thejaws 10-10 when the door sections are straightened out. 22 is a recessor hole in the tongue into which the nose 16 of the latch drops so as tolock together both sections of the latch mechanism and hold the doorsections in the straightened out position. Projecting laterally from thetongue is a. wing which is provided with a hole or passage 23, which isarranged to line up with the out-side hole or passage 19 of the latch,so that the hasp of a padlock may be passed throughv these holes 19-23to positively lock the latch in its holding position. 24 is a loopextending outwardly from the base 20 and forwardly to the tongue 21 toform a hand-hold, said loop also bracing and strengthening the parts. Onthe 'opposite side of the door from the latch proper is located a handleor lever 25, which is properly secured to the end of the spindle 12, sothat by swinging said lever the latch may be operated from that side.This lever 25 has one or two offsets 25a each forming in effect a bellcrank lever which may be used for operating an overhead bolt in themanner hereafter described. 26 is a keeper plate mounted on the dooradjacent-to the free end of the lever 25, the said keeper plat-e havingan offset bar 27. The end of the lever 25 may have a hole therein, sothat the hasp of a padlock may be passed through the same and under thekeeper bar 27 to lock the latch on that side of the door. overheadspring latch bolt 7 is mounted in a suitable case 7a, which may besecured to the door section upon which the aforesaid latch is located.The tail of this spring latch bolt 7 may be connected by a chain or wire28 with the arm 18 of the latch (or with one of the bell cranks 25L ofthe lever 25) so that whenthe latch proper is lifted, it willsimultaneously and automatically retract the spring latch bolt 7 therebyat once unlocking the two door sections 1-2 so that they may be buckled,and unlocking the door sections from the overhead casing to permit saidbuckling of the door sections. In the drawings, Fig. 6, I have shown thespring latch bolt 7 as connected by wire to the bell crank arm of thelever 25, because in that particular figure, the door is intended tobuckle outwardly, and obviously the latch bolt7 should always be on theindoor side. If the door were designed to buckle inwardly, then thelatch mechanism would be located on the inside of the door underneaththe spring latch bolt 7, and the wire 28, in that event, would beconnected with the arm 18 of the latch. If the door had a lower boltcorresponding to the bolt 7, its connecting wire would be connected tothe latch through the hole 19a. If it were desired to have a springlatch bolt in the lower edge of the door to take into a keeper on thedoor sill, it is obvious that such an arrangement could be provided, inwhich event'another latch bolt 7 like that shown inv Fig. 6 would beprovided for the lower edge of the door.

No separate illustration is required because this mere duplication isVerfectly obvious.

lVhen the doors stan ajar, as shown in dotted lines of Fig. 2, they maybe easily The I closed by grasping the hand-hold 24 and pulling the sameto the right as viewed in said figure. As the doors straighten out, theedge of the tongue 21 engages the bev eled edge 162l of the latch, so asto automatically lift the same. It then enters the socket space betweenthe jaws 10-10, so that the doors will be held against independentvertical movement and so that when the doors are fully straightened out,the nose 16 of the latch will drop down into the hole 22 so as tosecurely hold the door secl tions in the straightened out or in closedposition shown in solid lines Fig. 2. The stop 17 serves to hold thelatch in the proper position when the doors are buckled, sothat whensaid doors are closing, the tongue 21 will properly'engage the bevel 16ato lift the latch. The case 7'c1 for the latch bolt 7 is of cylindricalform, and is provided at diametrically opposite edges with twocorresponding flanges, one of which is shown at 7b. The flanges receivethe bolts or screws by which the case is secured to the door,

the whole of said case stood above the surface or" the door, it wouldtend to limit the deoree to which the doors could be brought c ctogether when folded back.

It will be understood that I have shown and described my invention onlyin its preferred form, and that I fully appreciate that variousmodilications in the design and arrangement of parts may be had withoutdeparting from the spirit and scope of my invention.
